Because these may take a long time to run, we recommend starting them before you leave at the end of your day so they can run over night.
1. Reboot your computer and press the f12 key as soon as you see the
Dell screen that shows right before the Windows screen. If you miss it,
just wait for Windows to finish starting and try again.
2. Now you should see the black boot menu screen. From here it
depends on which model of computer you have, but the steps are similar for all.
3. Use the up/down arrows to select “Diagnostics” or “Utility
Partition” or something similar and press the enter key.
4. A few pre-boot tests may run and ask you some questions. Answer as
best you can (these tests aren’t important now). At the end of these tests
press any key to boot the utility partition.
5. Then the hardware diagnostics screen comes up while loading some
software, and then a menu with 4 buttons. Click on the “Custom Tests”
6. Check the Non-interactive tests only box near the top of the window
and select “All Devices” from the tree on the left.
7. Click “Run Tests” button.
8. Email or call the Help Desk with whatever error messages you get. If you
don’t get an error message, then your issue is probably software or network
